Teachers and school librarians with access to a mixture of old and new computers may wish to connect older computers to a digital projector in the classroom to share presentations, demonstrations, or guided tutorials with students or faculty. In order to connect older computers to digital projectors, a DVI to VGA adapter is needed. The adapter is used to connect an external projector with a VGA cable to a DVI port (monitor out port) on a laptop or computer. DVI (Digital Video Interface) is a newer form of video technology that displays images at a high quality resolution. VGA (Video Graphics Array) is an older basic standard for resolution that displays images at a very low resolution. DVI to VGA adapters are commonly used by anyone to connect devices that have older video cards with another device that can display high resolution images. Adapters come in a variety of models because computers are made with 'monitor out' ports in many different shapes and sizes. Therefore one must match the make and model of their computer and projector to the appropriate model adapter. To find out what model adapter best suits a particular computer and projector, it is best to contact customer service of the manufacturer of the projector. InFocus is a popular brand projector used in classrooms. Their customer service FAQ matches the appropriate model adapter to specific models of computers. School librarians sometimes have as many as five different models of these adapters on hand to support the variety of computers, laptops, and projectors used for teaching.
